WLB in GE

Off-deals: probably 50-60 hours per week. Assuming your job is mostly sourcing, it's a high volume of work but it's predictable and relatively within your control if you want to chill 1-2 nights a week. No CEO is going to ask you to take an intro call at 10:00 at night on short notice.  

Live deals: Depends to a pretty large extent on your firm's strategy... if you're doing growth buyouts this can probably be every bit as insane and detail oriented as your classic PE firm. If you guys are doing a ton of smaller checks, or if you are primarily following / coinvesting in rounds, this will be a lot lighter since 1) there's less to diligence in the first place if it's a smaller / less complex company, 2) you can draft off someone else's work, and 3) the company is gonna tell you to piss off if you make their life difficult as a relatively small shareholder.
